[Detailed description of the invention] This invention relates to a switch with a lamp display.The purpose of this invention is to check the load status from the switch mounting position in cases such as gate lights and warehouse lighting where the load status cannot be confirmed from the switch mounting position. To provide a switch with a lamp display that can be checked, can light up the display lamp with stable switch operation, and can be easily incorporated with the display lamp.

The present invention will be explained in detail below with reference to embodiment figures.

A contact pattern surface 12.13 is formed on the lower surface of the substrate 3 with which the contact spring piece 10.11 comes into contact, and a resistor for current limiting protection is provided on the upper surface of the contact pattern surface 12.13. A resistor 14 and an indicator lamp 5 are arranged, and the indicator lamp 5 is connected in series with a resistor 14, and both ends of the series circuit are connected to the contact pattern surfaces 12, 13 of the substrate 3, respectively.

A display window 4 is formed on one side of the switch bundle 2, and a display lamp 5 is disposed inside the display window 4.

Further, a display label 15 is placed on the upper surface of the switch bundle 2, and a transparent cover 16 is removably fitted thereon, and a lamp cover 4a is mounted on the display window 4.

Reference numeral 6 denotes a load terminal device disposed on one side of the lower part of the switch body 1 together with the display circuit terminal device 7. These terminal devices 6 and 7 each have a terminal plate 18, a lock piece 19a and a contact piece 1.
9b and a lock release button 20 shared by both terminal devices 6 and 7, contact spring pieces 10. 11 is fixed in contact with the terminal plate 18 of the load terminal device 6.
A fixed contact plate 21 is integrally connected to the.

Reference numeral 8 denotes a power terminal device disposed on the other side of the lower part of the switch body 1, which includes a terminal plate 24 in which a contact plate 23 having a contact support part 22 is connected, a locking piece 25a and a contact piece 2 as described above.
5b, and a lock release button 26 for unlocking the pair of lock springs 25, 25.

The switch section 9 is composed of the contact 27 supported by the contact support section 22 and the fixed contact plate, and the contact 2
By penetrating the substrate 3 and bendably disposing a reversing spring 28 between the switch handle 2 and the switch handle 2, the contactor 27 and the fixed contact plate 21 respond to the operation of the switch handle 2.
Contact and separation are performed.

The above-mentioned switch with a lamp display has a circuit configuration as shown in FIG. becomes conductive, and the load terminal device 6
A circuit is established from the contact spring piece 10, the contact pattern surface 12 of the board 3, the resistor 14, the indicator lamp 5, the contact pattern surface 13, and the contact spring piece 11 to the display circuit terminal device 7, and the load The fact that the power supply 30 is connected to the circuit No. 29 is indicated by the lighting of the indicator lamp 5.

As described above, the present invention includes a resistor for current limiting protection wired on a board, a contact pattern surface formed on the bottom surface of the board, and a resistor connected in series to the resistor for current limiting protection. It comprises an indicator lamp attached and arranged in the indicator window of the switch handle, and a load terminal device and an indicator circuit terminal device arranged on one side of the switch body, the load terminal device and the indicator circuit terminal device respectively. Since it is electrically connected to the board via the contact spring piece, it is now possible to incorporate an indicator lamp for displaying the load status into the switch body. There is no need to take the time and effort to combine multiple switches, so even if a large number of switches are installed so that the load status can be displayed, wiring errors will not occur. This has the effect of reducing the required installation space since it is not required, and since the load status can be easily determined from the switch mounting part, it has the effect of preventing forgetting to turn off the load. Since the switch part of the indicator lamp is constructed using the contact pattern surface, stable performance can be obtained and reliable lighting operation of the indicator lamp can be achieved.In addition, the indicator lamp and the resistor for current limiting protection can be mounted on the board. Since it is attached, it has the advantage of being easy to incorporate into the switch handle.

In addition, the bases of the contact spring pieces are placed in contact with each other on the terminal plate of each terminal device, and the free ends of the plate-shaped contact spring pieces are elastically attached to the contact pattern surface of the corresponding board, so that the contact spring pieces are inserted into the holes. The contact spring piece can be inserted between the terminal board and the board without having to insert it through the terminal or fix it with fixing parts such as rivets, which eliminates the need for complicated assembly work and is effective for small switches. Moreover, since the contact spring pieces are plate-shaped, stable contact can be obtained compared to those using wire members, there is no disadvantage that the indicator lamp flickers during use, and the load terminal The device and the display circuit terminal device are each provided with a terminal board and a locking spring having a locking piece and a contact piece, and a common locking release button is provided so that the electric wire can be attached and detached from outside the switch body. Therefore, the connection space can be reduced compared to the case where external loads are connected using terminal screws, and the advantage is that it can be made smaller while incorporating a built-in indicator lamp while maintaining assembly and operational performance. has.
